Purpose: Explore acceptability of vaccines in development: cancer, Type II diabetes, Alzheimer’s disease, Lyme disease, Ebola, and obesity. Research questions: To what extent does acceptability vary by vaccine type? To what extent does acceptability of vaccines in development vary by race and other key demographics? To what extent are general vaccine hesitancy and key demographics associated with acceptability of vaccines in development? Design: Cross-sectional online survey administered through GfK’s KnowledgePanel in 2015. Analysis completed in 2020. Subjects: Nationally representative sample of Black and White American adults (n = 1,643). Measures: Willingness to accept a novel vaccine was measured on a 4-point Likert scale. Independent variables included demographics (e.g. age, race, gender) and measures of vaccine hesitancy, trust, and the “Three C’s” of vaccine confidence, complacency, and convenience. Analysis: Exploratory analysis including descriptive statistics and regression modeling. Results: Acceptability varied from 77% for a cancer vaccine to 55% for an obesity vaccine. White race, male gender, older age, having a chronic health condition, and higher socioeconomic status were associated with higher acceptability. Higher vaccine confidence and lower vaccine hesitancy were predictors for acceptability. Conclusion: The success of a vaccine depends on widespread public acceptance. Vaccine hesitancy may hinder acceptance of future vaccines, with significant differences by demographics. Future social science research is necessary to better understand and address vaccine hesitancy.

Proof-of-concept for a virus-induced obesity vaccine; vaccination against the obesity agent adenovirus 36

Human adenovirus 36 (Ad36) is positively associated with obesity in humans and animals. Ad36 infection is characterized by increased adiposity and inflammation. To investigate the possibility that a prophylactic vaccine candidate might protect against Ad36-induced obesity and inflammation, we purified Ad36 and ultraviolet-irradiated virus to obtain a vaccine candidate. After immunizing the mice with the vaccine candidate (vaccinated group), live Ad36 was injected into mice as a challenge test. Unvaccinated mice (control group) were immunized with phosphate-buffered saline and then challenged with live Ad36. Fourteen weeks after challenge, we compared adiposity and inflammation in vaccinated and control mice. The control group showed 17% greater body weight and 20% more epididymal fats compared with the vaccinated group. In addition, the vaccinated group had decreased serum levels of pro-inflammatory cytokines, and infiltrated immune cells, especially M1 macrophages, in fat tissue. Therefore, the vaccine candidate for Ad36 was able to protect against Ad36-increased body weight and fat as well as inflammatory states after challenge. These results provide proof-of-concept for prophylactic vaccination against virus-induced adiposity.

Review

Author: Monteiro, Mariana P

Obesity is one of the largest and fastest growing public health problems in the world. Last century social changes have set an obesogenic milieu that calls for micro and macro environment interventions for disease prevention, while treatment is mandatory for individuals already obese. The cornerstone of overweight and obesity treatment is diet and physical exercise. However, many patients find lifestyle modifications difficult to comply and prone to failure in the long-term; therefore many patients consider anti-obesity drugs an important adjuvant if not a better alternative to behavioral approach or obesity surgery. Since the pharmacological options for obesity treatment remain quite limited, this is an exciting research area, with new treatment targets and strategies on the horizon. This review discusses the development of innovative therapeutic agents, focusing in energy homeostasis regulation and the use of molecular vaccines, targeting hormones such as somatostatin, GIP and ghrelin, to reduce body weight.
